A properly authored video DVD --- mpg2 files without without menu but this the proper navigation for the DVD player -- will hold 60 minutes of video at the best resolution. Ignore file size. You can try to fit the videos to disc but the quality will go down. You have to decide how much you can accept.

You can always try using DL DVD media. .

I have done discs before with two one hour tv shows on each disc using a Coral prog (30 day trial) I am now just trying to do the same thing with PD. Both files properties say 1.3Gb but PD says two of them come to 7.6GB and are too big for the disc.I am getting some dual layer discs but I don't understand how it is 7.6Gb?

If you are making [b]data disc[/b], you can certainly put more on a single sided DVD. That is just copying the TV shows to a disc to play them on a computer or a TV that will play video files.

If you are making a true video disc (like a purchased DVD) and you compress the video to a lower quality, you can get up to about 2 hours on a disc. Anything beyond that may give an unwatchable quality, the disc will hang being produced or the disc will drop off some of the video. Commercial movie discs are double layer.

Did you cut out the commercials? In my part of the world TV shows are not one hour long.

If you used the Corel software, the quality was reduced. It just did not tell you it was going to do that.

Thanks stevek, The videos are of TV progs with no commercials. I think the first lot had already been converted and compressed, I'm not sure, but on the TV the quality looked ok. The lot I'm trying to do haven't been converted or had anything done to them. My son is bringing some Dual Layer discs aound, that's probably what I should be using anyway. I'll update after I try again. Thanks again.
PS, here we have the good old BBC which doesn't have commercials.
